[Nexus 5 Q&A, Help & Troubleshooting] Eskimo128:
My wife and I both have Nexus 5's, and have 3 Vu chargers between us.. Her N5 is in the Google bumper case, mine in a Cruzerlite case. She sits her N5 in the Vu all day at work to use as a clock.

We've had one instance of a hot phone in January, but in the ~200 placements between hers and mine, it's only happened once - I guess we're lucky, as she used to place the phone on the angled side of the Vu and let it slide down into place..exactly what could trigger the 3rd coil.
[Nexus 5 Q&A, Help & Troubleshooting] EvilTechie:
alrighty, i signed up just to answer this very specific question

lol

I have the diztronic black matte TPU case, and yes, i still get overheating utilizing the "new" docking method of tilt and rest

the battery temp was about 48.1C / 119F when i checked

which i dont consider normal

it seems like 3rd coil was activated still...

im changing to i-blason candygel hybrid case now but it seems pretty thick too so i dont know if it will be any different

will report back regardless
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Yes, 119F is too hot. Probably is the case. Since I've been pivot docking the problem is gone. Been many months now.
[Nexus 5 Q&A, Help & Troubleshooting] wideasleep1:
Same...neither my Nexus 4 nor 5 have gone hot, both wearing Diz cases, using the Tylt-in method.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
If you're into it and you really like those cases and the tylt, there is info in the thread on how to disable the 3rd coil.
[Nexus 5 Q&A, Help & Troubleshooting] adivorandroid:
Hello!

can you suggest any application android for monitoring current ampere charging from my qi charger?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
What's wrong with the monitor built in to the phone?
[Nexus 5 Q&A, Help & Troubleshooting] EvilTechie:
i emailed Tylt customer service

they said they have made a revision and is sending me one for RMA
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
The revision has nothing to do with the overheating problem.
[Nexus 5 Q&A, Help & Troubleshooting] EvilTechie:
I know eh... But how do I tell their customer service that they are wrong and we are right lol

Like someone said in this thread, their CS is a bit clueless.

Or are they sending me a vu with 3rd coil disabled?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
No, I guess they are trying to make you feel like they are doing something. They did the same for me but when asked they will tell you that this fixes some devices that don't fully charge or something and has nothing to do with the Nexus 5 overheating problem. They will tell you that their position is that the official fix is the special pivot docking procedure and they don't intend to issue any hardware fixes for the N5.
[Nexus 5 Q&A, Help & Troubleshooting] adivorandroid:
how can i use this? Sorry but i'm not an expert :(

With my old samsung i used a application that show current ampere charging on my screen . Easy Easy

I'm looking similar application for nexus....if exist

Samsung app: https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
[Nexus 5 Q&A, Help & Troubleshooting] EvilTechie:
here is my email to their CS trying to get more response out of them

and this is their CS reply
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
It's easy enough to test. If you very slowly slide it down you should activate the 3rd coil. I would be very surprised if anything at all has changed. I was clearly advised that they had no plans to address that issue. If they actually changed it then they told all of us a different story to avoid having a mass recall.

Please be careful and test it so we can be certain. Thanks.
[Nexus 5 Q&A, Help & Troubleshooting] EvilTechie:
still getting very hot with the new Vu they sent me

I received the new charger on Saturday and tried it overnight. It still gets pretty hot, with the peak of 113.18F (45.1C) on Saturday night and 111F (44C) last night.

is this temperature normal at all? or is it damaging the PCB and components inside the phone, battery included?

I am using Battery Monitor Widget to monitor it

so I believe these are battery readings and not motherboard readings

seeing where the 3rd coil is, PCB temp is probably even higher

and now Tylt's customer service is saying:

im tired of this and just want a Qi charger that works without doing any damage to my phone

any suggestions?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Like I said, despite what they told you the mods they made in the one they sent you have absolutely nothing to do with the Nexus 5 3rd coil overheating problem. Yours is however not overheating at the temps you stated.

Those temps you are seeing may be reasonable if your battery is more than 1/3 low or so and I wouldn't be too concerned. Keep in mind the tylt charges very quickly for a qi charger and the high charge current produces some heat. If you are using daydream you can shut that off and it will drop the charge temp a bit.

I've had my two tylts about 8 months or so and my N5 has had no heat related issues at all. If that 3rd coil kicks in it will quickly go north of 125F and then you can worry. But that just doesn't happen if you dock it properly. So if you come home drunk plug it in that night rather than docking it.
[Nexus 5 Q&A, Help & Troubleshooting] jabadala:
I'm absolutely confused. I've tried the landscape docking method as well as the aforementioned vertical drop in method and still get the overheating issue from time to time. Anyone else having the same issue? I'm thinking about snipping the third coil but don't want to void warranty since my charger is exhibiting odd behavior.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Are you sure it's actually overheating? How hot is it getting?
[Nexus 5 Q&A, Help & Troubleshooting] hithereperson:
Thanks. I did this now but I didn't test if it will get hot or not, however the charger is still working fine as it detects the Nexus 5 normally and the light goes green, so it should be ok.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I

The light being green doesn't mean it's not going to overheat. Hi temp is only indication.

If you actually disconnected the top coil then I don't think it can overheat.
[Nexus 5 Q&A, Help & Troubleshooting] andy o:
Is there any record of this happening with other phones? BTW, I don't think the N5 has magnets as stated in the first post.

So this just happened to me last night. Put the phone in at night, and it started charging, no problem. After a short time I noticed the screen turned on (I have the xposed option for it to turn on when it charges, but not sure if that triggered it). I just went back to sleep thinking that it would just turn off in a few seconds since it was on the lockscreen.

I woke up to my phone turned off and super hot, almost too hot to touch. The records in Battery Monitor Widget say that around 46 °C the phone stops taking in current, but it also shows the charger stays on. Normally this will start to cool down the phone, but here it just kept going up and at the 58.8 °C mark the history stops (phone turns off).
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
The N5 doesn't have magnets, it has metal to attract to magnets.

There are phones like the oneplus one that overheat when using an addon Qi receiver.
[Nexus 5 Q&A, Help & Troubleshooting] velopirate:
I have the same two concerns as you do with the Tylt Vu. I am experiencing the same behavior at night with both my Nexus 6 and my Galaxy S6. I will try their suggestion of making sure that the phone touches the base of the charger first, but my experience has been that if I do that, 80% of the time the charger never recognizes the phone and the phone doesn't charge.
[Nexus 5 Q&A, Help & Troubleshooting] pewdy:
Same here but with a Galaxy S6

I had the same problem with a TYLT charger. Heated up my Galaxy S6 to really high temp. It was obvious to me that Qi charging does something with magnets to heat up phones. Just my experience.

Returned my TYLT charger to Amazon.com for a refund. Back to using a good ole USB cable to plug in and charge phone the old-fashioned way, where the phone remains cool to touch. Thank you.

Maybe the industry will get this stuff right eventually with Qi chargers for all phone models. Until then, plenty of complaints as you see. :mad:
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I contacted tylt a few days ago and they said they are running tests to see what the issue is with the heat on the N5. They actually advised to stop using it until they sorted it out. I haven't left it unattended but I have been using it and it really seems to have settled down. I really think they definitely have the nicest Qi charger on the market and decent tech support so I'm going to give them a chance and in the meantime avoid leaving the N5 on the charger unattended for long periods of time.
[Nexus 5 Q&A, Help & Troubleshooting] Shinyhead:
Good idea... I might just return it for now and pick up a couple DT-900s...
[Nexus 5 Q&A, Help & Troubleshooting] PearcePowers:
I contacted Tylt as well. Their response to me was to send my unit in so they could test it (and they would ship me a new unit). However, I haven't had the issue again (yet!) since it first happened and I've also been monitoring it closely whenever charging my devices. Not sure if the problem lies with the phone or the charger or some hybrid of the two. It's a very nice charger, and as long as it doesn't happen again, I'm good with that.

However, once the official Nexus wireless charging pad comes out, I'll be switching to that for home use. I'll take the Tylt to work, where it will be easier to monitor while in use.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Got to wonder if it had something to do with something unusual about the state of a brand new battery? Seems like there is some kind of pattern with the overheat only happening with the brand new phones?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
tylt got back to me. They said they tested many units now with the Nexus 5 and couldn't reproduce the overheating issue an any of them. So they want to send me a replacement for mine that caused overheating the one isolated time.
[Nexus 5 Q&A, Help & Troubleshooting] EmperorX:
Well. Sounds like I need to buy one now!
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I do like the way they support the product and aside from the one isolated overheating incident I think it's by far the best Qi charger I've seen. It does run a bit warmer than a USB charger under normal use but I'm thinking that's just the nature of wireless charging.
[Nexus 5 Q&A, Help & Troubleshooting] westentertainer:
i use a powerqi no heat what so ever and fully charged in the morning
[Nexus 5 Q&A, Help & Troubleshooting] pekeltje:
Im using this one:

Works good, not as fast as cable but pretty fast.

I havnt used a normal charger since i use this Qi Charger.

Using it as a stand while charging in on my desk.
[Nexus 5 Q&A, Help & Troubleshooting] gotzaDroid:
Not at all, but that's for two reasons. 1) I have the LG wireless orb, so I'm not worried about quality and 2) if it was that bad, then why would Google have LG build it into the nexus line?
[Nexus 5 Q&A, Help & Troubleshooting] busab:
I am using the Vu and have not had a problem. My temperature tops out at around 100F it looks like.
[Nexus 5 Q&A, Help & Troubleshooting] EmperorX:
Ok. Purchasing now. Thanks man!
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Actually I was specifically talking about the tylt, not the orb.

Google builds the coils into the phone, the charger you choose to use can be any compatible Qi charger.

My one-time overheating issue happened like the 2nd day I had the phone. The 20-30 degree rise during charging was also while it was days old. IMO getting some component broken in (charger, battery or both) fixed the one-time overheating and the normal charging temp rise is now down to about 10-15 degrees. I would bet that even your orb produces that much rise.

But FWIW, 10 degrees is still higher than USB charging and any additional heat means additional wear. Of course YMMV.

I assume Google is selling it because they feel the convenience is worth the additional wear. Make no mistake it is harder on your battery.

In my case I think it's worth the extra battery wear because when the battery is finally hosed I will either get a new phone or attempt to personally replace the battery. While replacing the battery is going to be a pain and an extra expense neither seems that terribly objectionable to me at this point.

There is a possibility that the original battery will still be fairly strong at that time I'm done with the N5 but I'm hard on the battery and I doubt that will be the case. Besides, my wife will probably take the phone from me when I'm done and I wouldn't want her to have worn battery.

Thats what I'm seeing now but it was much hotter during the first week. BTW, what are you using for the temp charting?
[Nexus 5 Q&A, Help & Troubleshooting] 3's&7's:
I am using my n5 on a tylt with no issues whatsoever; surface temperature is barely elevated.

Charges quickly, even with Spigen slim armor case on. The Tylt performs to spec and fast on my n5.
[Nexus 5 Q&A, Help & Troubleshooting] jzsax1:
i too have experience this behavior using the QI standard Wireless Charger. The Nexus 7 works as advertised. The Nexus 5 overheats and i can sometimes find it loop booting. It doesn't do it all the time and i haven't been able to see a pattern as to when it does it...
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Did it happen more than once? Did it perhaps only happen when the phone was only a day or two old?

FWIW tylt is replacing mine even though it seems to function normally now.
[Nexus 5 Q&A, Help & Troubleshooting] Birdsfan:
I just had my first experience with the phone getting hot on the VU. Something you mentioned in the OP seems to be a (at least for me) a common thread. I had just finished charging my N4 when I immediately swapped it our for my N5. My N5 a few hours later was hot/off/didn't charge. I wonder if having a different device on the charger has something to do with it. I have had zero issues with the VU up until yesterday with my N5 (got it the Monday after launch) until I tried back to back charging with 2 different phones.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
That wasn't the case when mine did the overheat thing but is certainly a cause for concern. Do you know the battery temp by chance when it overheated? I use an app called systempanel that will give me the battery temp. I'm sure there a many apps out there that do the same.
[Nexus 5 Q&A, Help & Troubleshooting] Birdsfan:
No idea unfortunately, it was 1:00ish in the am, not at 100% mental capacity...
[Nexus 5 Q&A, Help & Troubleshooting] EmperorX:
FYI, the official Google Qi charger is now in the play store! I just snagged one
[Nexus 5 Q&A, Help & Troubleshooting] jakiah:
Outch

Just got mine today - same thing.

I went to pick up my Nexus 5 after 4 hours on the charger and it was like I touched a stovetop. Not warm... HOT AS HELL! (Charging Vertically)

The phone was off, LED on the VU was green the whole time. I tried to restart after five minutes, no go. It shut off after the boot animation. Had to wait another 5 before the phone would power on. Only got to a 53% charge, not sure of temp.

Boo :(
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Thats exactly how mine did, including the 53%. And, don't know how new your phone is but it sounds like your charger was brand new which is also consistent with the other incidents.

If it's like the rest, at least so far, it's been a one-time event. I've been continuing to use and monitor mine. I just don't leave it on there too long without checking on it. So far, aside from the one time when it was brand new, its been perfect. Tylt still wants to send me a replacement but they haven't made changes because they can't reproduce it. If it's a one-time event when the charger is first used, I'm going to watch that replacement VERY carefully the first few times.
[Nexus 5 Q&A, Help & Troubleshooting] jzsax1:
well after the experience i had with the boot loop and the extreme heat coming from the device i decided not to use it... i just use it with the Nexus 7 because it just works...no issues... i have two Nexus 7 models and the pad works fine with them... why does it not work well with the five is beyond me and i rather not take chances and fry my device...
[Nexus 5 Q&A, Help & Troubleshooting] sohell:
Does anyone know if the Nexus 5 can charge via a Qi charger if the mobile is switched off?

Thanks
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
my tylt appears to charge while off. I did notice however that the light flow controlled led doesn't flash while charging. Still appears to charge.

---------- Post added at 04:16 PM ---------- Previous post was at 04:14 PM ----------

BTW, my Tylt seems to have broken in with a pretty regular battery charge temp of 108F.
[Nexus 5 Q&A, Help & Troubleshooting] Momotani-Hitoshi:
Been using the Tylt Vu with my Nexus 5 the past week just fine until yesterday.

My nexus was drained to 5%, I put it on the tylt went to bed. This morning it was burn hot! So hot I couldn't hold it in my hand. The Tylt Vu was also hot. Usually, it is just warm to the touch not oven hot. Battery only charged to 32% too. I guess it got stuck there and overheated.
[Nexus 5 Q&A, Help & Troubleshooting] Tweaken:
Wow, glad I saw this thread. I almost bought one yesterday. Looks like I'll be getting the Nokia DT-910 charging stand instead. I already have the Nokia DT-900 flat charger which works fine (doesn't work with a Nexus 4 by the way).
[Nexus 5 Q&A, Help & Troubleshooting] Nitemare3219:
Maybe the distance from the charger has something to do with the overheating potential...

Those of you who have had issues, can you post what case you were using, if any?

I'm using a Slim Armor and haven't had any issues, but I've only used the charger about 5 times. Charger is black and ordered from T-Mobile about a week ago.

Sent from my Nexus 5
[Nexus 5 Q&A, Help & Troubleshooting] Momotani-Hitoshi:
Not using any case right now. Don't think its distance related. Normally it is just barely warm when charging, but when it over heating wow it was hot couldn't even hold it.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
This strange overheat seems to happen to most tylt users (including myself) ONCE. For no apparent reason at all. So far I have not seen anyone report it happening more than once. Case doesn't matter, nor does orientation or alignment. Tylt has tried to reproduce with the N5 and never been able to see it.

BTW, I have another thread for users to report their battery heatup during normal Qi charging and so far the tylt and the nokia have been the hottest. See first post below.

[Nexus 5 Q&A, Help & Troubleshooting] Momotani-Hitoshi:
Hmm it only happens once? Does the N5 get smart or something and remember it got baked too hot and started protecting itself lol?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
So far it's unexplainable. I can just say that as of yet I haven't seen a report of more than once. That said, some have quit after their initial big charging surprise. I already owned two tylts before the N5 was released. I was one of the first to receive my N5. The overheating with no charge happened like the 2nd night and hasn't happened since.

Hey, YMMV lol.
[Nexus 5 Q&A, Help & Troubleshooting] r_3:
Same thing has happened to me a couple times. Tylt from T-Mobile. N5 completely stock. Ringke slim case.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Thanks, this is the first report of multiple occurrences that I've seen. Not only has my tylt never overheated again, the maximum normal charge temp has mysteriously dropped by over 10 degrees to around 100F. Been charging at that temp for over a week. Before that it was consistently 110±
[Nexus 5 Q&A, Help & Troubleshooting] r_3:
I should try my n7 to see if it has the same issue, but I am worried it will fry it :(
[Nexus 5 Q&A, Help & Troubleshooting] Momotani-Hitoshi:
Install "Battery Monitor Widget" and set a battery temperature threshold alarm so when it over heats you will know. Been monitoring my nexus 5 since I had the first overheating incident. So far it hasn't gotten to the point where I couldn't hold it again, but once it did reach near 48C while charging and got a bit hot.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
what we need is a failsafe app that will shut down the phone based on a temp threshold. The alarm isn't nearly enough if I'm asleep. I'll bet you could whip something up in Tasker fairly easily.

Two nights in a row... Nexus 5 overheat on Tylt VU

Thanks for the info everyone, I'm glad I'm not alone. I posted the details earlier today in this thread, and am providing the quote below:

Another test for me tonight. I'm curious to see what I will discover in the morning. :/
[Nexus 5 Q&A, Help & Troubleshooting] Shinyhead:
I just returned the tylt vu and plan on using my dt-900s instead. Dont want to take a chance with this heating issue.. :confused:
[Nexus 5 Q&A, Help & Troubleshooting] Lipmonger:
OK... so before going to bed the other night, I rebooted my phone and reset the charger (just unplugged it and plugged it back in at the wall). No issues that night. 100% charge in the morning! However, I started having overheating this morning with my Tylt charger at work. And I think I figured out what's going on...

PROBLEM: THE SCREEN STAYS ON!

I happened to glance over at my phone just now, and noticed that the screen was actually on. The phone was locked (the lock screen was displayed), but the display was SIGNIFICANTLY dimmed. I mean, insanely barely-even-on dimmed. It's barely visible, and at a setting that is below any brightness setting I've ever seen. As soon as I picked up the phone, it went back to normal brightness. I then typed in my unlock code, relocked the phone, set it back on the Tylt charger, and all was normal.

For whatever reason, I think my N5 isn't always shutting its screen off on the Tylt charger, which I think is causing this overheating. It's draining the battery probably just as fast as it is charging it, in this weird "super-dimmed" mode.

I don't know if I can get it to repeat the weird dimming mode it goes into, but if I can, I'll post a photo.

UPDATE:

I just noticed that the phone also goes into this dimmed mode RIGHT before the screen shuts off for the true "sleep" mode. It dims for about 2 seconds, and then the screen-off animation occurs. I'm guessing that the phone is getting stuck at that dim point when placed on the Tylt. Anyone else notice this?
[Nexus 5 Q&A, Help & Troubleshooting] jakiah:
Come to think of it, I believe I had a dream active when it happened to me. I turned it off because it is too dim to be usable at that angle on the charger. Hmmmmm.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I couldn't swear to it because it only happened once and it was a while ago but it seems familiar. I'll certainly take notice if it happens again.

Nice work!
[Nexus 5 Q&A, Help & Troubleshooting] Tweaken:
Still really want to get this charger. Has anyone had an overheating issue since the update to 4.4.2?
[Nexus 5 Q&A, Help & Troubleshooting] pcloadletter1:

[Nexus 5 Q&A, Help & Troubleshooting] Momotani-Hitoshi:
Mine over heated once and then got pretty warm another time, but haven't had any issue since. Im on 4.4.2 now.

Wonder if it is just the nexus stuck on a process or something causing excess heat.
[Nexus 5 Q&A, Help & Troubleshooting] stbxxl:
No. I also noticed that after turning off Day Dream the N5 gets less warm during wireless charging - even with the TYLT. Perhaps in average 4-5 °C.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I turned off dream last night to see if made a difference with mine. I was over 50% low. The battery got up to 100F but often it goes over 106F on 50% charge. So turning off dream does appear to help. I need to monitor for a while to confirm for certain. Thanks for the tip.
